IDEA: Natural line sorting in file

(1/1)

TucknDar:
Ok, I suppose any decent text editor should be able to sort lines based on alphabet or numbers, but I'm looking for a tool that can sort lines based on Natural order sorting, i.e.

from this:
1. some text
10. yet more text
1011. Text
2. more text again
4. more text

--- End quote ---
to:
1. some text
2. more text again
4. more text
10. yet more text
1011. Text

--- End quote ---

No GUI necessary, btw. command line tool would be perfect :)

thanks!

I've done an algorithm for excel using the Windows API function in XP... someone might be able to use that to simplify things.

The Unix "sort -n" command will do this easily.

$ clip
1. some text
10. yet more text
1011. Text
2. more text again
4. more text

skwire@hankoku ~
$ clip | sort -n
1. some text
2. more text again
4. more text
10. yet more text
1011. Text

I've attached a Win32 binary version of the Unix sort command.
